The round thing on the top of the module is the regulator. The pump sends fuel to the regulator at a certain pressure. The regulator decreases the pressure to match what the motor requires. This means that there is more fuel going to the regulator than is needed by the motor. Any excess fuel is squirt back into the tank.


A clear view of the pump inside the module.


Remove the 4 screws holding in the pump bracket and here is the pump (culprit?).


Nice QC (quality control). Look at the rubber bushing. Geezus!
